本文分享了解决App启动时Launcher报错的经验，通过版本回退及对比，定位到问题源于启动时的默认Launcher处理，屏蔽后问题解决。

App 启动launcher时报错,总是启动不了,没有具体异常显示,只有一个Activity启动time out 的提示.每个APP的环境都不一样.我只能提供我解决这个问题的思路.
1.使用git回退版本,找最近的版本,或二分查找法,可以找到一个正常和有错误的版本(临近),在这两个版本之间做比较,看看是自己哪些修改导致了这个错误.
2.一般出现这个错误都是在app启动做了什么修改导致,回想一下最近做了什么launcher修改,把它屏蔽掉试试看.而我的情况就是在app启动的时候做了默认launcher处理导致的.把它屏蔽掉就okay了.

前言 很高兴遇见你~ 欢迎阅读我的文章 这篇文章讲解关于window token的问题，同时也是Context机制和Window机制这两篇文章的一个补充。如果你对Android的Window机制和Context机制目前位了解过，强烈建议你先阅读前面两篇文章，可以帮助理解整个源码的解析过程以及对token的理解。同时文章涉及到Activty启动流程源码，读者可先阅读Activity启动流程这篇文章。文章涉及到这些方面的内容默认读者已经阅读且了解，不会对这方面的内容过多阐述，如果遇到一些内容不理解，可以找到对应
显示Activity组件的启动窗口（Starting Window）的过程分析

在Android系统中，Activity组件在启动之后，并且在它的窗口显示出来之前，可以显示一个启动窗口。这个启动窗口可以看作是Activity组件的预览窗口，是由WindowManagerService服务统一管理的，即由WindowManagerService服务负责启动和结束。 Activity组件的启动窗口是由ActivityManagerService服务来决定是否要显示的。如果需要显示，那么ActivityManagerService服务就会通知WindowManagerService服务来为正

最新发布
12-05
<think>我们注意到这个错误信息与之前的问题相同，都是因为本地修改导致无法切换分支（checkout）而中断同步。具体来说，在同步过程中，当尝试检出`platform/hardware/samsung/nfcerror`仓库时，发现该仓库存在未提交的修改（具体文件是`libs/WindowManager/Shell/src/com/android/wm/shell/splitscreen/SplitScreenTransitions.java`），因此同步被中止，并且导致后续的`frameworks/base`仓库也无法检出。 ### 解决步骤： 1. **定位问题仓库**：根据错误信息，问题出在`platform/hardware/samsung/nfcerror`仓库。 2. **处理该仓库的本地修改**：有两种选择： - **保存修改**：将修改临时提交（commit），然后继续同步，同步完成后再处理这些修改。 - **放弃修改**：如果这些修改不需要保留，可以直接丢弃。 #### 方法一：保存修改（推荐） ```bash # 进入问题仓库 cd platform/hardware/samsung/nfcerror # 将当前修改添加到暂存区并提交（这是一个临时提交，后续可以修改或撤销） git add -A git commit -m "临时提交：保存本地修改以便同步" # 回到项目根目录 cd ../../../.. # 重新执行同步 repo sync ``` #### 方法二：放弃修改 ```bash # 进入问题仓库 cd platform/hardware/samsung/nfcerror # 丢弃所有本地修改（包括未跟踪的文件） git reset --hard HEAD git clean -fd # 回到项目根目录 cd ../../../.. # 重新执行同步（可以加上`-f`强制覆盖） repo sync ``` #### 方法三：仅同步问题仓库（如果其他仓库已经同步成功） ```bash # 先同步问题仓库（强制覆盖） repo sync -f platform/hardware/samsung/nfcerror # 然后同步之前失败的frameworks/base仓库 repo sync -f frameworks/base # 最后再整体同步一次以确保其他仓库正常 repo sync ``` ### 注意事项： - 如果同步过程中出现多个仓库有问题，需要依次处理。 - 如果问题仓库的修改很重要，建议使用方法一（临时提交），同步后再使用`git rebase`或`git reset`重新整理提交。 - 如果问题仓库的修改不重要，可以直接使用方法二。 ### 预防措施： - 在同步代码前，使用`repo status`检查所有仓库的状态，确保没有未提交的修改。 - 对于不需要修改的仓库，可以在同步前使用`repo forall -c 'git reset --hard; git clean -fd'`命令清理所有仓库的修改（谨慎使用，会丢失所有未提交的修改）。 §§相关问题§§ 1. 在Android源码开发中，如何一次性检查所有仓库是否存在未提交的修改？ 2. 使用`repo forall`命令清理所有仓库的本地修改时，如何避免误删重要更改？ 3. 如果多个仓库同时存在未提交的修改，如何批量处理这些修改（如全部提交或全部丢弃）？ 4. 如何配置repo工具在同步时自动忽略某些仓库的修改（例如测试仓库）？ 5. 当同步过程中出现多个仓库失败时，如何编写脚本自动处理这些失败？ </think> ### 错误分析与解决方案 #### 核心问题定位 错误信息明确显示： ```bash platform/hardware/samsung/nfcerror: Your local changes to the following files would be overwritten by checkout: libs/WindowManager/Shell/src/com/android/wm/shell/splitscreen/SplitScreenTransitions.java error: Cannot checkout platform/frameworks/base error: Exited sync due to checkout errors Failing repos: frameworks/base ``` #### 根本原因 1. **本地修改冲突**： - `platform/hardware/samsung/nfcerror` 仓库中存在未提交的本地修改 - repo sync 需要覆盖这些修改才能切换分支/版本 2. **连锁反应**： - 该仓库的错误导致整个同步过程中断 - 关键仓库 `frameworks/base` 无法完成检出 --- ### 解决方案步骤 #### 方法1：提交本地修改后同步（推荐） ```bash # 进入问题仓库目录 cd platform/hardware/samsung/nfcerror # 添加并提交所有修改 git add -A git commit -m "临时提交: 保存本地修改以完成sync" # 返回项目根目录 cd ../../../.. # 继续同步 repo sync ``` #### 方法2：放弃本地修改后强制同步 ```bash # 进入问题仓库目录 cd platform/hardware/samsung/nfcerror # 丢弃所有未提交修改 git reset --hard HEAD # 清理未跟踪文件 git clean -fd # 返回项目根目录 cd ../../../.. # 强制同步（包含中断的仓库） repo sync -f ``` #### 方法3：单独同步失败仓库 ```bash # 先同步问题仓库 repo sync -f platform/hardware/samsung/nfcerror # 再同步关键仓库 repo sync -f frameworks/base # 最后完整同步 repo sync ``` --- ### 高级技巧：批量处理多个冲突仓库 如果存在多个仓库冲突： ```bash # 1. 检查所有冲突仓库 repo status | grep -B 1 "modified:" | grep "project" # 2. 批量丢弃修改 repo forall -c 'git reset --hard HEAD; git clean -fd' # 3. 强制同步 repo sync -f ``` --- ### 预防措施 1. **同步前检查**： ```bash repo status ``` 2. **使用临时分支**： ```bash repo start temp-sync-branch --all repo sync ``` 3. **忽略特定仓库**： 在 `.repo/local_manifests` 创建排除文件： ```xml <?xml version="1.0" encoding="UTF-8"?> <manifest> <remove-project name="platform/hardware/samsung/nfcerror" /> </manifest> ```
